lifting systems. It also contains a second two man living chamber which

also doubles up as an eight man HRC for diver rescue in times of

emergencies. It also includes all ancillary equipment to safely carry out

extended saturation diving operations.

3.2.1 Diver Transport

The SDC is a 200 meter diving-bell with an internal and external working

pressure of 20 bars. The bell mates onto the chamber by horizontal hub,

divers’ exit via vertical hub. Electrical supply and communications are

provided by means of the Electro mechanical cable in the main bell

umbilical. Gas is supplied by means of the main bell umbilic al with back up

gas supplied from 8 onboard gas cylinders mounted on the outside of the

diving-bell. Hot water can be supplied from the surface for divers hot water

suits Electrical heating of the divers’ suits.

3.2.2 Hyperbaric Rescue Chamber and Control Van

The system includes a Hyperbaric Rescue Chamber and a separate

Control Van which is embarked on a separate standby vessel or on land if

close enough. The HRC CV provides the facility to manage the HRC when

it has been deployed. It contains the necessary panels, communications

and analysis equipment to be able to monitor and control the

decompression of divers and to control the environment inside the HRC.

It also contains the hoses and interconnect cables required to mate with

the HRC. The system also requires that sufficient gas is stored with the

HRC CV to enable treatment and decompression of the divers.

The HRC is monitored in normal operations through the Saturation CV

and can be deployed by a number of means including a gravity

deployment system if the height is not too great or by crane.

3.2.3 Compression and decompression

Internal working pressure of chamber is 30 bar. Internal diameter 1,800mm x

length 3,800mm. Main chamber contains four beds. The decompression chamber is equipped with two separate control panels (one for the main chamber and one for the lock) for the gas, power and communications systems. The mating of the diving-bell to the decompression chamber is

carried out by a manual clamp with a pneumatic safety interlock that prevents accidental removal of the clamp and depressurization of the bell and or chamber hydraulic clamp.

The second living chamber consists of two bunks. The mating of the first chamber to second chamber is carried out with a clamp in a similar manner as

stated above.

3.2.4 Handling System

The diving-bell is transferred from the decompression chamber to the

dive position by means of a pivoting hydraulic handling A Frame. (The

pivoting movement functions by means of hydraulic rams). The hydraulic

lifting winch of 4.OT has a speed of 20m/min. The diving-bell is guided

by guide lines maintained in constant tension by pneumatic winches.

3.2.5 Standard Equipment

The system comes complete with a colour video system with video

overlay, full analysis capability, a complete array of helium unscrambler

radios for diving and life support functions as well as a full range of tools

and spares for the system equipment.

The environmental control system (ECS) consists of 2 major assemblies:

Control Master Unit (CMU).

Habitat Conditioning Unit (HCU)

The CMU’s provides fluid for temperature (primary circuit) and humidity

(secondary circuit) control. The CMU comprises a condensing refrigeration

system, a fluid heating system, primary f luid pump, secondary fluid pump,

associated mixing valves and electronic controls to allow automation.

The HCU’s are installed in the chamber and translate fluid input into

heating, cooling and dehumidification functions. Gas is circulated through

the HCU by means of electrically powered blowers, the primary electrical

fan blows gas across the primary heat exchanger and on through the soda

lime canister. The secondary electrical blower blows gas across the

secondary heat exchanger to dehumidify the gas. A water trap is situated

under the unit to catch condensed water for locking out of the chamber.

Note: The units fitted are modified Kinergetics HCU-3-4 units; the normal

water driven motor is replaced by 2 electrically powered motors. The

modification was designed and carried out by Clearbrook Engineering.

5. VOLUME TANKS FOR HOT & COLD WATER

Each chamber is supplied with both hot and cold water from the domestic

hot and cold water tanks. There is 1 hot water tank and 1 cold water tank

in the chamber complex; the tanks are supplied from the water main.

Once the tanks are filled, regulated gas is used to pressurise the tank

forcing the water out the bottom of the tank into the chamber. The hot

water tank has an immersion heater, with thermostat, fitted to heat the

water. Check valves are fitted to prevent back pressurising the water

main. The cold water tank also supplies the humidifier in the work

chamber. The water is supplied to the chamber sinks and shower through

isolation valves.

6. VOLUME TANK FOR SANITARY SYSTEM 6.1 SANITATION

All toilet waste is piped to the waste holding tank which is used to

vent off the pressure and then emptied into an external waste tank.

6.2 BILGE DRAINS

All the bilge and sink drains are piped to the same waste holding

tank as the sanitation waste.
